Am I correct assuming 1 sample of stereo frames will be written 44100
times by a rate of 44100 Hz audio sampled data?
Whereby one sample contains 2 frames. For one second, this would be a
sized array of:
CHANNELS = 2
buffer_size_per_second = CHANNELS * 44100 * sizeof(signed short);

The code should be correct rather a problem with the thread tree, once
more.

This is how the buffer is allocated. Strange to me is
multi_frames = buffer_length;
or
multi_frames = sndfile->file->info->channels * buffer_length;
gives about the same size of file.
/* buffer */
devout->buffer = (signed short **) malloc(4 * sizeof(signed short*));
devout->buffer[0] = (signed short *) malloc(devout->dsp_channels *
devout->buffer_size * sizeof(signed short));
devout->buffer[1] = (signed short *) malloc(devout->dsp_channels *

void
ags_sndfile_write(AgsPlayable *playable, signed short *buffer, guint
buffer_length)
{
AgsSndfile *sndfile;
sf_count_t multi_frames, retval;
sndfile = AGS_SNDFILE(playable);
multi_frames = buffer_length;
retval = sf_write_short(sndfile->file, buffer, multi_frames);
If buffer_length gives the number of bytes of the buffer,
you may be in trouble here. For sf_write_short, /usr/include/sndfile.h
says:
** All of these read/write function return number of items read/written.
